The configuration is such that the set value of the setting item can be adjusted. Hereinafter, the adjustment dial 3 will be described.

As shown in FIG. 1, the adjustment dial 3 includes a dial body 31 and an F sensor 41 serving as a position detecting means.
And an R sensor 43, a code plate (not shown), and a conductive brush. In this case, the rotation amount detecting means 30 is constituted by the code plate and the brush.

The dial body 31 is installed rotatably with respect to the camera body 2. As will be described later, the dial body 31 is rotated in a predetermined direction to adjust set values of setting items.

The code plate is installed concentrically on the back side of the dial body 31 (inside the camera 1) so that it can rotate together with the dial body 31. A predetermined conductor (conductive) pattern (not shown) is formed on the back surface of the code plate so that a signal (information) corresponding to the amount of rotation of the dial body 31 can be input to the control means 7. That is, on the back surface of the code plate, two identical conductor patterns are arranged at predetermined intervals.

The brush is arranged such that one end is connected to a circuit formed on a printed board (not shown) and the other end is in contact with the back surface (the surface on which the conductor pattern is formed) of the code plate. I have. The dial body 3
The "rotation amount" of 1 is not the absolute value of the rotation amount,
This is a concept that includes the direction of rotation and its amount. That is,

Hereinafter, the case where the conductive members 411 and 412 are conductive by contacting the conductive members 411 and 412 is referred to as “F sensor 41 is on”, and the case where the conductive members 411 and 412 are not conductive is referred to as “F sensor 41 is off”.

Such an F sensor 41 is arranged so that only the central portion thereof is exposed to the outside of the camera body 2, and is attached to the camera body 2 at insulating members 413 and 414 by fasteners (not shown). The reason why the F sensor 41 and the R sensor 43 are arranged at the above positions is as follows.

FIGS. 3 and 4 are a perspective view showing a state where the adjustment dial 3 is operated with a thumb and a perspective view showing a state where the adjustment dial 3 is operated with an index finger, respectively. As shown in FIG. 3, when the dial main body 31 of the adjustment dial 3 is operated by the thumb, it is usually operated from the rear side (the left side in FIG. 3) of the camera main body 2, and as shown in FIG. 3
When the camera 1 is operated with the index finger, the camera 1 is usually operated from the front side (the right side in FIG. 4) of the camera body 2. This is for the purpose.

When adjusting the set value using the adjustment dial 3, the photographer selects a setting item by selecting the position of a finger to be operated, and the dial body 31.
The set value is adjusted by rotating.

Next, the operation of the adjustment dial 3 will be described. As shown in FIG. 3, when the adjustment dial 3 is operated from the back side of the camera body 2 with a thumb and a finger contacts only the R sensor 43, only the R sensor 43 is turned on. As shown in FIG. 4, when the adjustment dial 3 is operated with the index finger from the front side of the camera body 2 and the finger contacts only the F sensor 41, only the F sensor 41 is turned on.

Although not shown, the finger is connected to the F sensor 41.
When the finger contacts the F sensor 41 and the R sensor 43, the F sensor 41 and the R sensor 43 turn on.
The F sensor 41 and the R sensor 43 are off.

FIG. 5 is a block diagram showing a configuration example of the camera 1. As shown in the figure, signals (information) from the F sensor 41 and the R sensor 43 are respectively input to the control means 7.

When the dial body 31 of the adjustment dial 3 is rotated, the code plate is also rotated, whereby the rotation detecting means 30 detects the direction of rotation from the conduction timing of the conductor pattern and corresponds to the amount of rotation. Then, a signal for increasing or decreasing the set value of the setting item is input to the control means 7.

More specifically, as shown in FIG. 5, when the dial main body 31 is rotated in a predetermined direction by one step, a signal for increasing the set value by one step from the rotation amount detecting means 30 to the control means 7 (hereinafter, referred to as a signal). When the dial body 31 is rotated by one step in the direction opposite to the above direction, a signal for lowering the set value by one step from the rotation amount detecting means 30 to the control means 7 (hereinafter, referred to as a data down signal). ) Is entered. Thus, the rotation amount detecting means 3
From 0, a predetermined number of data-up signals or data-down signals are input to the control means 7 in accordance with the amount of rotation of the dial body 31, that is, the number of steps and the direction of rotation.

The control means 7 is usually constituted by a microcomputer, and updates setting items and setting values based on each signal input from the adjustment dial 3 and other signals, and a memory (not shown). To memorize. The operation of the control means 7 based on each signal input from the adjustment dial 3 will be described later in detail.

The control means 7 sends an operation signal according to the setting and adjustment to the shutter driving means 9 and the aperture driving means 1.
0, the light is output to the photometric unit 11, the distance measuring unit 12, and the film feeding unit 13, and these units are respectively driven according to predetermined settings. In addition, the control unit 7 controls various functions of the camera 1 such as sequence control, execution of autofocus, exposure calculation, and the like as needed.

The main switch 8 is a switch for selecting ON / OFF of the power supply of the camera 1. Main switch 8
Is input to the control means 7, the control means 7 controls so that the functions of each part of the camera 1 can be operated. The photometric unit 11 measures the luminance of the subject using a light receiving element, and the obtained information (photometric information) is input to the control unit 7.

The distance measuring means 12 measures distance information from the camera 1 to a subject or a defocus amount with respect to a reference focus position (focus position) in the camera 1 by, for example, an active method or a passive method. The information (distance measurement information) is input to the control means 7. The film feeding means 13 is means for winding up the film by one frame after shooting.

The release switch 5 is composed of a two-stage switch. When the first stage of the release switch 5 is turned on, the photometric means 11 and the distance measuring means 12 are operated, respectively.
When the second stage is turned on, the aperture is operated by the aperture driving means 10 and the shutter is operated by the shutter driving means 9 to perform photographing.

In this case, for example, when the photographing mode of the camera 1 is set to "manual", photographing is performed with the shutter speed and the aperture value adjusted by the adjustment dial 3.

When the setting of the photographing mode of the camera 1 is "aperture priority" and "shutter speed priority", the control means 7 based on the photometric information from the photometric means 11 in order to obtain an appropriate exposure amount. Exposure calculation is performed by the calculation unit, and the shutter speed is determined in the case of “aperture priority”, and the aperture value is determined in the case of “shutter speed priority”.

That is, in the case of "aperture priority", shooting is performed at the aperture value adjusted by the adjustment dial 3 and the determined shutter speed, and the "shutter speed priority" is set.
In the case of, shooting is performed with the shutter speed adjusted by the adjustment dial 3 and the determined aperture value.

The display section 6 is usually provided with a liquid crystal display panel (LC).
D) and the like. In the display section 6, the adjustment dial 3 is controlled in accordance with an output signal from the control means 7.
Settings and adjustments, etc., and other items (for example,
Date and time) are displayed.

FIGS. 6 and 7 are flowcharts each showing the operation of the control means 7 during photographing. FIG. 6 is a main program, and FIG. 7 is a subroutine program corresponding to step 101 in the main program shown in FIG. Hereinafter, each flowchart will be described.

As shown in FIG. 6, in the main program, first, the setting information set by operating the adjustment dial 3 and the like, that is, the setting for inputting the photographing mode, exposure correction, shutter speed, aperture value, drive and the like. A value input process is executed (step 101).

FIG. 7 is a diagram showing details of the set value input processing. In this subroutine program, it is determined whether or not a data up signal has been input from the rotation amount detecting means 30 of the adjustment dial 3 (step 201). ), Step 2
In 01, when it is determined that the data up signal has been input, it is determined whether or not the F sensor 41 is turned on (step 202).

In step 202, the F sensor 41
If it is determined that the R sensor 43 is on, it is determined whether or not the R sensor 43 is on (step 203). If it is determined in step 203 that the R sensor 43 is on, " The set value of "exposure correction" is increased by one level (step 204). That is, the F sensor 41
When both the R sensor 43 and the R sensor 43 are on, the exposure can be corrected by the adjustment dial 3.

If it is determined in step 203 that the R sensor 43 is off, the set value of the "shutter speed (Tv value)" is increased by one step (step 205). If it is determined in step 202 that the F sensor 41 is off, it is determined whether the R sensor 43 is on (step 20).
6) If it is determined in step 206 that the R sensor 43 is on, the set value of the "aperture value (Av value)" is increased by one step (step 207).

If it is determined in step 206 that the R sensor 43 is off, the set value of "drive" is increased by one (step 208).
That is, when both the F sensor 41 and the R sensor 43 are off, the drive mode can be set by the adjustment dial 3. In the case of a drive, for example, a case where the adjustment is performed in the order of “single-shot shooting” → “continuous shooting” → “self-timer shooting” is called an increase in the set value, and a case where the adjustment is performed in the reverse order is the set value It is called down.

Next, it is determined whether or not a data down signal has been input from the rotation amount detecting means 30 of the adjustment dial 3 (step 209). If it is determined in step 209 that the data down signal has been input, F is determined. It is determined whether or not the sensor 41 is turned on (step 21)
0).

In step 210, the F sensor 41
If it is determined that the R sensor 43 is on, it is determined whether the R sensor 43 is on (step 211). If it is determined in step 211 that the R sensor 43 is on, " The set value of "exposure correction" is reduced by one step (step 212).

If it is determined in step 211 that the R sensor 43 is off, the set value of "shutter speed (Tv value)" is reduced by one step (step 213). If it is determined in step 210 that the F sensor 41 is off, it is determined whether the R sensor 43 is on (step 21).
4) If it is determined in step 214 that the R sensor 43 is on, the set value of the "aperture value (Av value)" is reduced by one step (step 215).

If it is determined in step 214 that the R sensor 43 is off, the set value of "drive" is reduced by one step (step 216).
This is the end of the subroutine program, and returns to the main program. Each time the data up signal or the data down signal is input, the set value increases or decreases by one step.

As shown in FIG. 6, each set value adjusted by the adjustment dial 3 or the like is input (step 101).
Thereafter, it is determined whether or not the first stage of the release switch 5 has been turned on (step 102). If it is determined in step 102 that the first stage of the release switch 5 has been turned on, the photometry means 11 and the distance measurement means 12 operate,
Photometry information and distance measurement information are input (step 103).

Next, based on the photometric information from the photometric means 11, exposure calculation is performed in the arithmetic section of the control means 7, and a focusing operation of a photographic lens (not shown) based on the distance measurement information from the distance measuring means 12. Is performed (step 104).

Next, it is determined whether or not the second stage of the release switch 5 has been turned on (step 105).
If it is determined in 05 that the second stage of the release switch 5 has been turned on, shooting is performed in a predetermined shooting mode (step 106).

That is, when the photographing mode of the camera 1 is set to “manual”, photographing is performed with the shutter speed and the aperture value adjusted by the adjustment dial 3. In the case of “aperture priority”, the aperture value adjusted by the adjustment dial 3 and the shutter speed determined by the exposure calculation, and in the case of “shutter speed priority”, the shutter adjusted by the adjustment dial 3 Photographing is performed with the speed and the aperture value determined by the exposure calculation. When the photographing is completed, the film is wound up by one frame by the film feeding means 13 (step 107). This ends the program.

As described above, according to the adjustment dial 3 of this embodiment, there is an advantage that selection of a setting item and adjustment of the setting value of the setting item can be performed with one operation.
This simplifies the operation for adjusting the set value as compared with the related art, and enables quick adjustment of the set value.
